BATON ROUGE, LA Tests found a “highly el­e­vated” blood al­co­hol level in the body of a Louisiana State Univer­sity stu­dent whose death po­lice are in­ves­ti­gat­ing as a pos­si­ble re­sult of fra­ter­nity hazing, a coro­ner said Fri­day.

Pre­lim­i­nary au­topsy re­sults Fri­day found no in­ter­nal or ex­ter­nal trauma, but did find swelling in the brain and lungs of Maxwell Ray­mond Gru­ver, 18. Tests also de­tected the pres­ence of mar­i­juana.

Gru­ver, from Roswell, Ga., a can­di­date for mem­ber­ship in the Phi Delta Theta fra­ter­nity, died Thurs­day.
